To all whom it may coofoern:

Beit known that I, Ammo F. MAsuRY, a citizen of the United States, andresidingin the borough of-Manhattan of the city of New York, countyof'New York, in the'State of New Yor'k,have invented certain new and 1useful Improvementsin Sheet-Metal Intervtion in nal-Combustion Engines,.ofwhich thefollowing is a specification, reference being had to theaccompanying drawings, forming "a' part hereof. i

Thisinvention-relates to internal combusti n casings formed of sheetmetal and has for itsgeneral object to provide a construcwhich thesections of the casing may be pressed readily into symmetrical partsfrom integral blanks and then united per manently to form the completecasing. In:

.ternal combustion engine casings of this type while possessing manymechanical ads vantages over cast structures are diflicultto manufacturein. such form as will'satisfy manufacturing considerations, and at thesame tiine give the necessary' .strength and .111 service. The

I each section the crank case .walls and cylinder section walls areintegral withone an other and the proximate edges of the two sectionsare flanged to permit their perma-' nent' union and the formation of theunitary engine body- Within the cylinder section walls may be supportedthe other, elements such as the cylinders and the'top and bot tom platesby which the cylinders are supclearly from the illustrated embodiment,in which,'

concerned with its form or the means for applying it to the improved"casing. The

cylinder section of the casing consists of two symmetrical sectionsindicated generally by the reference characters a and each of thesesections includes side walls a, end walls a integral with the said a forthe crank case, and side walls a therefor, all of'the said walls in eachsuch sectionbeing stamped from a single integral blank vices availablein the art other way known to the art. In addition to the openings a forthe bearings of the crank shaft the walls a fof the crankcase may havestampedtherein suitable handholes a as is usual in crankcase'constructions.

Within the engine walls proper there may side walls, end Walls by anysuitable defor handling metal. ach section has formed, in the endWalls'abe supported adjacent the top and bottom horizontal plates 6 in whichare formed openings 6 alined in the respectlve plates to receive thecylinders c of the motor.

These plates aresupported within the sheet metal .walls of the casing'byriveting, weldtop and bottom plates by some such method. en thepartsare'given their permanent set necessarv, of course, that the topand bottom after formation of'the engine body it ismg or otherwise, andthe cylinders 0 may be secured intheir respective openlngs 1n thedisposed with. relation 7 to the engine Walls and cranlr and thecylinders so mounted in said plates that the cylinders shall bemaintained in parallelism and in proper relation to the moving parts ofthe motor.

The construction described has the ad vantage that the two sections amay be pressed from a single blank of sheet metal, the walls or": theengine and the crank case in each section being integral, and that thesetWo sections may be readily united along the transverse line of unionindicated by the flanges a. I

It is to be under tood that the invention is not to be limited to theprecise form or size of any of the parts mentioned nor to the particularmeans employed for uniting any of the contracting metallic parts sinceall such details Will depend upon the character of the motor to beformed and to metal Working considerations which may best be optionalwith those skilled that particular art.

I claim as my invention:

1. A sheet metal casing for an internal combustion engine formed ofsections united along transverse planes, the Walls of the cylindersection and the crank case in each section being formed in one integralpiece from a single piece of sheet metal.

2. A sheet metal casing for an internal combustion engine formed of twosections united along a transverse plane passing substantially throughthe mid-section of the engine, the walls of the cylinder section and thecrank case in each section being formed from a single piece of sheetmetal.

3. 1%. sheet metal casing for an internal combustion engine formed oftwo sections united along a transverse plane passing substantiallythrough the mid-section of the engine, the Walls of the cylinder sectionand the crank case in each section being formed from a single piece ofsheet metal, with openings formed in the end walls of the crank case toreceive the crank shaft.

4. A sheet metal casing. for an internal combustion engine formed ofsections united along transverse lanes, the Walls of the cylindersection andthe crank case in each section being formed in one integralpiece from a single piece of sheet metal, and top and bottom platessecured permanently Within the engine Walls and having openings toreceive the cylinders.

5. A sheet metal casing for an internal combustion engine formed ofsections united along transverse planes, the Walls of the cylindersection and the crank case in each section being formed in one integralpiece from a single piece of sheet metal, with flanges formed along theproximate edges of adjacent sections, and means to secure the flangestogether.
